Answer:
numbers are 3x,2x,5x
so 3x+2x+5x=10x=840
so x=84
so numbers are 252,168,420
Answer:
B. 5.4
Step-by-step explanation:
3/5 = 6/10
6/10 = 0.6
9 x 0.6 = 5.4
Answer:
17x(1 -2y)
Step-by-step explanation:
34xy = 17x * 2y
17x - 34xy = 17x - 17x*2y
=17x( 1 - 2y)
Answer:
140
Step-by-step explanation:
AEF and DFE are opposite interior angles, so they are equal to each other
you can set the equation to 2x + 60 = 3x + 20
subtract 2x from both sides: 60 = x + 20
subtract 20 from both sides: 40 = x
plug in the value of x to the equation for AEF: 2(40) + 60
you get AEF is 140
WHat else is to the question?!?
